Abstract (en)

[origin: WO9949960A1] An internal batch mixing machine (20) includes a mixing chamber and oppositely driven first and second rotors (22, 24). The first rotor has a pair of lobes located in its first and third quadrants (96, 98; 100', 102'), while the second rotor has a pair of lobes (120, 122; 124', 126') located in its second and fourth quadrants. One of the lobes (96, 98) of each pair is longer than the other, and extends downstream at an acute co-helix angle toward the other lobe (98, 116'). The leading end of the long lobe is near one end of its rotor, and the short lobe is at the other end. Material adjacent the longer lobe are pushed away from its end and toward the other end of that rotor. Additionally, the trailing ends of each pair of lobes forms a space which causes confluent material to be squeezed between the trailing ends thereby adding turbulence to further mix the material.
